Using d3.js with Apache Zeppelin

Question

I'm trying to add more visualization options to Apache Zeppelin by integrating it with d3.js

I found an example where someone did it with leaflet.js here, and tried to do something similar -- unfortunately I'm not too familiar with angularJS (what Zeppelin uses to interpret front end languages). I'm also not streaming data. Below is my code, using just a simple tutorial example from d3.js

%angular
<div>
    <svg class="chart"></svg>
</div>
<script>
function useD3() {
    var data = [4, 8, 15, 16, 23, 42];

    var width = 420,
        barHeight = 20;

    var x = d3.scale.linear()
        .domain([0, d3.max(data)])
        .range([0, width]);

    var chart = d3.select(".chart")
        .attr("width", width)
        .attr("height", barHeight * data.length);

    var bar = chart.selectAll("g")
        .data(data)
      .enter().append("g")
        .attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });

    bar.append("rect")
        .attr("width", x)
        .attr("height", barHeight - 1);
}

if (window.d3) {
    useD3();
} else {
    var sc = document.createElement('script');
    sc.type = 'text/javascript';
    sc.src = 'https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.16/d3.min.js';
    sc.onload = useD3;
    sc.onerror = function(err) { alert(err); }
    document.getElementsByTagName('head')[0].appendChild(sc);
}
</script>

However, in Zeppelin, it finishes running with no errors, and all I get is a blank div. Any help is appreciated.

The Zeppelin version is 0.7.0. The example works in this version. You could also use the html display system. The results are on the pictures.
